Yes I tried many linears before in some Gamingkeybords - But mainly Cherry MXs. The last one I had was black so I went to the Cherry clears because I liked the harder spring in the blacks. I also tried Gateron red and bought a punch of Gateron clears by accident because I thought they are similar to the Cherry clears 
Also tinkered around with Flaretech opticals (red, black and blue) some time ago on an optical keyboard just because I liked the idea of optical switches. But they are rather bad in my opinion.
Clickys are no option for me because I really dont like the noise... sry
Well, you could swap springs in the Gateron clears at least, if you wanted to make them heavier. What was wrong with the Flaretech opticals? I have never tried them. There are a few different manufacturers trying their hand at opticals now, hall effect too.
By the way I built a 60% bord with that Gateron clear only for gaming and this turned out really great. Although I like the linears for Gaming I dont like typing on them so I looked for tactile switches.
In my daily board I currently use lubed Holy Pandas with a 67g spring from durock. I like that combination a lot, they are very different to those Cherry MX clears but the same direction in some way - if you get what Im trying to say?
At the moment I am working on a KBD8x mkii in E-yellow with Zeal Zilent V2 - this should become as silent as possible for work, because I dont want to annoy all of my coworkers.
I could see Gateron clears being good for gaming. I have thought about box whites myself, since I prefer clickies. Something thunderous and/or highly tactile would distract me though. I'm still using MX reds in a Corsair K70 for gaming, because they're just good enough. Something a little heavier, or with a reasonable tactile event to prevent me from accidentally actuating them by resting my fingers on them would be nice though.
The closest thing to Holy Pandas I have tried is probably Halo Trues, because they came in my Drop ALT. I'm normally a clicky guy, and don't really like MX tactiles in general, but I'm open to trying more if the apocalypse ever ends and there happen to be more boutique/frankenswitch boards around at a meet or something. To me, MX tactiles (that I have tried) all feel just about the same other than how pronounced the tactile event is based on spring weighting and the stem used. In that way, it makes perfect sense to me that Holy Pandas and MX clears would seem similar to each other. I imagine lubrication made the biggest difference.
A lot of people love Zilent switches, so if you like MX tactiles I imagine you'll be happy with them. Especially so if you're prioritizing noise over feel. I have never tried them myself though.
I work in multiple schools, sometimes in the very middle of the library, and I use thunderous clicky keyboards almost exclusively. I have asked students and coworkers if they minded the switches I used multiple times. If they were relatively bassy, like SKCM blue Alps or box jades, nobody has ever minded them and many have liked hearing them. Some have disliked high-pitched clickies like MX blue or capacitive buckling spring, but I don't hear that often. If anybody ever reports that they mind them, I'll switch to something quieter. I wonder if anybody around you would really mind undampened tactile switches.
I'm using Matias' quiet "linear" switches right now, which aren't totally silent, but they're quieter than most rubber domes. I put linear in quotes because there's actually a tactile event at the bottom of travel ... which is quite a bit lower than actuation. I think they feel great though.
Do you have any switch recommendations that I should try? As I like soldering and tinkering around with stuff I am quite interested in any new stuff I can try.
As I said before, I'm no fan of MX or clones. The only tactile switches I have tried that I could find myself typing on regularly without a lot of effort to force myself is Alps and Matias. Their tactility is sharp and crisp, like a clicky. There are dampened varieties of both, although good Alps switches are getting harder and harder to find. I have found some stock "quiet click" as Matias calls them (they're dampened tactiles) to not be as perfectly smooth out of the box as their "linear" or clicky switches, but I have at least one used board that feels nice and smooth as well. They're still smoother than most unmodified MX and clone switches that I have tried out of the gate though.
If you like the rounded bump of most MX and clone switches, I couldn't help you other than maybe trying Topre. It is essentially a really refined rubber dome, which uses capacitive sensing on a PCB instead of a membrane. It is buttery smooth and a lot of people who like MX tactiles end up gravitating towards it once they've tried it. I have a 55g Topre board and it would definitely make my own shortlist of tactiles. There are a lot of threads about it all on here though. If you post what, specifically, you like in a tactile switch in the
Keyboards section, people who have done a lot more experimentation with MX tactiles than me could chime in.
